RE: Extending network over a dry pair

["Marshall, Quincy" <Quincy.Marshall () reged com>]

I used to take “dry pairs” or “alarm circuits” and take SDSL modems to create high bandwidth ( up to 10Mbps, relative 
to the time) circuits. They were very reliable and incredibly cheap (@$22-88/mo). Regional bell at the time (or at 
least in my area) would make it difficult to order. Had to find the order codes.

Looks like these new units are updates to what was around, but they were very testy on line quality/distance. the first 
rule … ‘no load’. Suggest trying the water in the shallow end first.

For a comparison of distance to capacity on copper, see

You might be able to pair bond -- if you had more than one pair.

If wireless isn't possible, you're likely needing satellite.

A quick question for you guys;

If you had a single dry pair (pair of copper wires originally for phones) to a remote site that was around 6 miles 
away, what would you use? We currently are just extending a T1 line to this site, but 1.5Mbps isn't cutting it anymore. 
Unfortunately it's a research site on a federally protected wildlife preserve so we can't run any new infrastructure 
(fiber etc) and it isn't in a geographical place where point to point wireless is practical. We were thinking there is 
some sort of network extender that uses some form of DSL for higher bandwidth capacity.

Any suggestions?

Look for an SHDSL Ethernet Extender
